Technical field
Sewage disposal device is the utility model is related to, more specifically to a kind of membrane bioreactor.
Background technology
In recent years, application of the membrane technology in sewage treatment field is particularly the membrane bioreaction combined with bioreactor
Device (Membrane Bioreactor, abbreviation MBR) technique is answered to be received increasingly as a kind of new and effective sewage treatment process
Extensive concern.MBR is a kind of new water technology for mutually tying platform with biological processing unit by film separation unit, with membrane module
Substitution secondary settling tank keeps high activity sludge concentration to reduce sewage treatment facility occupation of land in the bioreactor, and by keeping low dirt
Mud load reduces sludge quantity.There is MBR techniques easy to operate, hydraulic detention time (HRT) to be separated with sludge age (SRT), sludge
The advantages that concentration is high, capacity of resisting impact load is strong, effluent quality is good.In membrane bioreactor, bioreactor is mainly completed
The degraded of dirty water pollutant；Film separation unit mainly completes separation of solid and liquid and some macromolecular compounds is played with retention work
With used film is generally ultrafiltration or microfiltration membranes.
In practical applications, since the membrane module of MBR in the process of running is vulnerable to pollution, flux depression, shadow are caused
The stable operation of membrane module is rung, fouling membrane is become the key issue of limitation MBR applications.Fouling membrane refers to suspended particulate, colloid
Particle or dissolubility larger molecular organics adsorb deposition in film surface and fenestra, cause membrane aperture to reduce or block, lead to film
Measure the phenomenon declined.

One disturbing flow device, the disturbing flow device are clipped among pre-filter layer and biological film unit, can disturb between pre-filter layer and biomembrane
Sewage among unit, has membrane bioreactor circulation height, Membrane cleaning is convenient, the membrane operations cycle is long, operating cost is low
Advantage.
This method strengthens film surface cleaning performance by improving the turbulence intensity of liquid stream, to slow down film surface pollution thing deposition,
It is effective to improve cleaning efficiency, but since disturbance device is staticizer, film surface is cleaned by the kinetic energy of liquid stream, can not in reflux ratio
Can it is too big in the case of cleaning performance it is limited.
In addition, in existing MBR, generally also there are following defect：A. individually designed bottom aerating system is needed, equipment is multiple
It is miscellaneous huge, it is of high cost；B. film wire uses a bundle of structure, and such dirt or suspended matter can not rinse between being clipped in film wire；C. film
Silk is directly adopted after tying up and fastened with glue, and causes to cause film wire from film structure because long-time left-right and front-back is swung in operational process
In come off；D. fan energy consumption is high when aerating system is stirred using wind turbine；E. maintenance process is complicated, and equipment and technical staff are required
It is high.
